Don’t wait around to get invited for an interview about your book, or someone to write a review of your book, or someone to post it their blog. These things may or may not ever happen until you are discovered by enthusiasts of your genre.
Make noise because you’re your own best marketer. Be creative in your marketing. I already posted a post on the subject of “Creative Marketing”.
Don’t be shy. Talk to people about your books.
I am not saying any of the things above such as interviews, reviews and blog posting aren’t important because they are. They make your life easier as a writer. But when things don’t happen. You make things happen with your books. If one avenue isn’t working then try another, another, and another until something works.
